STEM Curricula: Are online courses good enough?


 


In my last post, I gave an example of how traditional science classes differ from multi-disciplinary, project based STEM (science, technology, engineering and math) classes.  It's important to consider how to engage your student in STEM programming, with new options popping up all the time. Some homeschooling parents use online curricula for traditional sciences, and these courses have validity and a solid place in education.  Unfortunately, I think online coursework for STEM only hits about half of the target.

It's true that part of what STEM offers could be learned from a textbook.  Its concepts are drawn from any of the physical sciences, technology, or mathematics and are often criss-crossed between two or more of these.  But STEM is much more: it's about learning how to communicate and interact well with peers in brainstorming, design, invention, innovation and collaboration.  These are the "soft" skills needed for the next generation of workers and they may seem obvious but require many hours of practice to master.  These are also the skills that an online course does not address.

I have taught STEM to five separate groups of homeschoolers (about 65 total students) over the past two years.  I have noticed that the skills that my STEM homeschooled students most need practice in are not vertical collaboration (ages above and below) but rather horizontal project collaboration (peer, same aged).  The homeschoolers I teach are wonderful, well-socialized and have good friends.  However, friendships are different from collaboration.  What my experience has shown me (this is not scientific, only observational) is that it takes nearly 30 hours of practice for homeschooled students to become very skilled in brainstorming and completing design projects together under constraints.  Acquiring STEM skills is less like charging through a textbook and more like apprenticing in a trade or growing a garden.  It takes time, mentoring and iteration.

So what is a parent to do?  My next post will have links to real-time (as opposed to virtual, online) STEM resources.  I'd love any and all comments and thoughts.

STEM for Homeschoolers

What is STEM and how is it different from science or math?

"STEM" or "STEM education" are hot topics right now, but they sound like you're into teaching plants or helping flowers.  The name itself is misleading.  STEM stands for science, technology, engineering and math, all lumped together in a handy dandy acronym.  So - not plants, but math and science loosely glued together?  No, that's not quite it either.  With this post I'm going to break down what STEM is and compare one day's science class versus STEM class.

What is STEM?

Although you can find umpteen definitions of STEM around, many agree on the following: STEM education combines multiple subjects together while using student-centered learning techniques.  It is an effort to bridge the gap between what a pure science class teaches (biology) and the skills a biological research scientist uses in a career (knows biology, but also needs to communicate well, design and test, use math to analyze data, and interact with other scientific professionals).  STEM education has a heavy focus on design, student initiative and "soft" skills such as collaboration, innovation and invention.

What's a real example of the difference between a science, math or computer class and a STEM class?

I teach several high school math and science courses at a co-op to homeschoolers, along with STEM classes, so I experience this every week. Here's the rundown of what happened on a recent day.

Physics class: we are studying periodic motion, and begin a unit on spring systems.  Students sit on chairs around a table and listen while I lecture and use the whiteboard.  I have several visuals to illustrate how springs work.  Students seem like they understand, and I prompt them for where they see springs in everyday life.  I do all my usual "teacher-ey" things to keep students engaged.  We do a lab exercise, where students in small groups measure data about springs.  I review what their lab report should look like.  End of class. The next class will continue with periodic motion.

STEM class:  Early in the year student groups brainstormed areas of interest in any STEM field.  One group picked alternative energy, so this day we are studying wind tunnels.  I arrive with a fan, clear containers and lots of tools.  After a brief lecture on how wind tunnels design, student groups spread out on the floor to make their own models. I walk between groups, making sure everyone is collaborating well.  While each group works, we talk about how to make smoke lines, how a mesh can help reduce wind turbulence, and what kind of turbines might work well.  We also brainstorm about where turbines could be placed.  We pack up and groups take their models home to finish. The next class will test our models and smoke lines.

Let's run that back.  Both classes were valuable.  Physics was concept-centered, and I used strategies to engage students including a hands-on lab.  STEM was also concept centered, but those concepts drew from multiple sciences and design work.  Students chose the topic and drove the flow of class, working with their peers the entire class.  Their end product will be a workable wind tunnels to test turbine prototypes, along with enhanced collaboration and design skills.

In coming posts I'll outline some age-specific STEM opportunities and what some barriers to STEM involvement are for homeschoolers.  If you have any experience with STEM and would like to add to the conversation, drop me a line at marycsaville@gmail.com or on twitter at @marycsaville.
